Precautions

Heat Treatment: Typically supplied in hot-rolled or normalized conditions; quenching and tempering can be applied for higher strength.

Surface Treatment: Galvanizing, painting, or other anti-corrosion treatments can extend service life based on environmental requirements.

Procurement Standards: Specify plate thickness, tolerance, impact test temperature (e.g., -20°C or -40°C), and delivery conditions.

Typical Manufacturers

Europe: ThyssenKrupp, ArcelorMittal.

China: Baowu Steel, Ansteel, Shougang (producing to European standards).
